摘要
针对新建矿山的首采阶段开拓工程量大的实际问题,可在开拓设计中对首采阶段适当采用组合阶段开拓,并对已施工的工程进行必要的改进,以节省基建工程量、节约投资,加速矿井建设。
In view of huge amount of level development work in initial mining stage of a newly-built mine, the proper use of combined level development system in initial mining stage and necessary improvements for some constructed work may result in fewer capital construction work and investment and faster construction speed.
